Specification forming part of Letters Patent No. 160,940, dated March 16, 1875; application led August 31, 1874.

To all whom it 'may concern:

Be it known that I, ISAAC MILLS, ot' Harnilton, Province of Ontario, Canada, have invented au Improvementin RalWay-Rail-JOiIIt Protectors, of which the following is a specication:

The nature of my invention consists in connecting the adjoining rails at the point at which they meet by the ordinary fish-plate, the same being fastened by bolts and nuts in the usual manner; and, further, in protecting the rail-joint and securing said fish-plate by means of a protector so constructed and arranged in connection with the outer surface of the rail that it shall enter and fit snugly between the nuts that fasten the rail, securely locking the same, while its upper surface eX- tends up Ilush with the rail-joint. I am aware that railroad-chairs have been so formed, or, in connection with the chair, a wedge or prot'ector has been used, the upper surface ot' which was flush with the rail-joint, and which received the tread of the wheel of the passing train, as contemplated in my'improvement, but in no instance have the chairs been so formed as to possess the additional function of securely locking the nuts on the bolts that fasten the fish-plate; and it is this double function-that is, of locking the nuts with its upper section extending up flush with the railjoint, so as to receive the tread of the wheelwhich distinguishes my improvement from previous inventions of this character, and which constitutes the value and importance of the same.

The construction and operation of my invention are as follows: A A are ordinary T- shaped rails, and B the chair, all formed an'd secured in the usual manner. C C are iishplates, and are also secured in the usual manner by bolts D D andnuts E E. F is thejointprotector, and may be made of any suitable material. I usually cast it in a single piece, weighing, say, about nine and a half pounds, and which renders it exceedingly cheap. The form of the joint-projector is clearly shown in the drawing. It fits closely against the fish4 plate, securely locking the nuts E E, while its upper surface, extending up tlush with the rails, insures the keeping` of the track in line and in surface, securely guarding and protecting the joints or end sections ot" the rail from all undue wear. The protector tits snugly down over the lip of the chair and its entire outer surface., and is secured to the sleeper by spikes H H. If desired, the `joint-protector F may be cast with a brace, G, and which will insure ot' its possessing, under all circumstances, the requisite degree of strength.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

The rails A A, ish -plates C C, secured by bolts D D and nuts E E, and the joint-protector F, the latter being secured in the manner shown, to act as a locking device for the nuts, the whole being combined and arranged to operate as and for the purpose specied.

In witness whereof I have signed my name to this specification in the presence of two subscribing witnesses.
